Water Masses in the Pacific in CCSM3
Publisher: American Meteorological Society
Abstract: An examination of model water masses in the North Pacific Ocean is performed in the Community Climate System version 3 (CCSM3) and its ocean-only counterpart. While the surface properties of the ocean are well represented ...
Water Mass Formation in an Isopycnal Model of the North Pacific
Publisher: American Meteorological Society
Abstract: An isopycnal model coupled with a mixed layer model is used to study transformation and formation rates in the North Pacific. When annual formation rates are averaged over the entire North Pacific, a large peak in water ...
Decadal Variability of North Pacific Central Mode Water
Publisher: American Meteorological Society
Abstract: An isopycnal model forced with wind stress and heat fluxes from 1965 through 1993 was used to examine the effects of variable atmospheric forcing on the ventilation of the North Pacific. During this time period, a climatic ...
Formation Mechanisms for North Pacific Central and Eastern Subtropical Mode Waters
Publisher: American Meteorological Society
Abstract: The effects of one-dimensional processes on the formation of deep mixed layers in the central mode water (CMW) and eastern subtropical mode water (ESMW) formation regions of the North Pacific have been analyzed using a ...
Geometrical Control of the Inertial Recirculation
Publisher: American Meteorological Society
Abstract: In this paper we discuss the conditions under which a free solution of the steady, one-layer, quasi-geostrophic equation on a ?-plane is realized in the inviscid limit. We restrict attention to the case where no body force ...
Mean Flow Evolution of a Baroclinically Unstable Potential Vorticity Front
Publisher: American Meteorological Society
Abstract: Quasi-linear theory and numerical models are used to study the mean flow modification of a two-layer shallow water baroclinically unstable flow as a function of Rossby number. This flow has an upper-layer potential vorticity ...
Lagrangian and Tracer Evolution in the Vicinity of an Unstable Jet
Publisher: American Meteorological Society
Abstract: The dynamics of Lagrangian particles and tracers in the vicinity of a baroclinically unstable zonal jet are investigated in a simple two-layer model with an initially quiescent lower layer. The presence of a growing wave ...
The Influence of Eddies on Tracer Transport in the Abyssal Ocean
Publisher: American Meteorological Society
Abstract: Tracer transport mechanisms in a deep western boundary current (DWBC) are explored using a three-layer, eddy-resolving quasigeostrophic model. The model is forced with a steady, sinusoidal wind stress. The effects of the ...
An Enhancement of Low-Frequency Variability in the Kuroshio–Oyashio Extension in CCSM3 owing to Ocean Model Biases
Publisher: American Meteorological Society
Abstract: Enhanced decadal variability in sea surface temperature (SST) centered on the Kuroshio Extension (KE) has been found in the Community Climate System Model version 3 (CCSM3) as well as in other coupled climate models. This ...
The Response of the North Pacific Ocean to Decadal Variability in Atmospheric Forcing: Wind versus Buoyancy Forcing
Publisher: American Meteorological Society
Abstract: Both wind and buoyancy forcing result in variability in the North Pacific Ocean thermocline. A vertical modal analysis of the density deviations in a 30-yr run of an ocean general circulation model of the North Pacific ...
